Answer:
45 inches
Step-by-step explanation:
If the larger rectangle is 72, then you divide it by 8 because that is the ratio of the bigger rectangle. 72/8 = 9 so that means that the scale value of the shapes is 9 because they are proportional. So, you multiply 9 time 5 to get 45 which is the smaller rectangle.

two numbers have the ratio of 4:7 if their sum is 143 what are the numbers?
1.kind of proportion
2.write the proportion
3.first number answer
4second number answer
help me plss!
Answer:
52:91
Step-by-step explanation:
To find a ratio value you need to think of it more as two numerators that together equal one whole. 4+7 is 11 so that would be the denominator. If the sum is 143, then we divide by 11 since one number is 4/11s of 143, and the other is 7/11s of 143. 143/11=13
now we multiply both:
4(13)=52
7(13)=91
Check:
91+52=143
52/91 simplifies to 4/7 or 4:7

Solve for x. Enter your answer in interval
notation using grouping symbols.
x2 + x < 20
Answer:
x<18
Step-by-step explanation:
2+x<20
Answer:
(-5, 4)
Step-by-step explanation:
x^2 + x < 20 can be rewritten as a quadratic in standard form: x^2 + x - 20 < 0. Recognize that the graph of x^2 + x - 20 is that of a parabola that opens up. Because the y-intercept (0, -20) is below the x-axis, we know for certain tht the graph intersects the x-axis in two places. Our job is to determine the two horizontal intercepts, which in turn determine the solution set.
x^2 + x - 20 = 0 factors as follows: (x + 5)(x - 4) = 0, whose roots are -5 and 4.
These two roots form 3 intervals: (-infinity, -5), (-5, 4) and (4, infinity). We now must identify on which intervals x^2 + x - 20 is less than 0 (that is, on which intervals the graph is below the x-axis). Choose three test values for x: the first could be -6 (which is in the set (-infinity, -5) ); x^2 + x - 20 is + there, and so the graph is above the x-axis and x^2 + x - 20 is positive. Reject this.
Next, test x = 0; x^2 + x - 20 is negative there, meaning that x^2 + x - 20 < 0 and that x^2 + x < 20. Thus, the solution is (-5, 4). It can be shown that x^2 + x - 20 is positive again for x-values within the interval (4, infinity).

Write the SLOPE INTERCEPT FORM of the equation of the line parallel to y=23x+19 through the point (6, 2). First to answer correctly gets brainliest!
Answer:
y = 23x - 136
Step-by-step explanation:
Since the lines are parallel, they have the same slope. So, the slope of the new line is 23 as well.
Now we have: y = 23x + b
plug in the points that are on this line (6,2) :
2 = 23 x 6 + b
2 = 138 +b
-136 = b
Line: y = 23x - 136

What is the magnitude and direction of the PQ with tail and head points P(-6, 0) and Q(2, 4)?
8.9 units, 63.4° north of east
8.9 units, 26.6° north of east
13.4 units, 180° west
13.4 units, 0° east
Answer:
What is the magnitude and direction of the PQ−→− with tail and head points P(-6, 0) and Q(2, 4)? magnitude = √(64+16) = √80 = appr 8.9 , ruling out c.
hope this helps
The magnitude of PQ is 8.9 and PQ is making an angle of 26.57° so 8.9 units, 26.6° north of east will be the correct answer.
What is a vector?A vector is a quantity in which direction and magnitude both matters called a vector.
A vector joining by two points (x₁,y₁) and (x₂,y₂) will be (x₂-x₁)[tex]\hat{i}[/tex] + (y₂-y₁)[tex]\hat{j}[/tex]
The magnitude of this vector will be
[tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2[/tex]
The direction of this vector will be
[tex]\\tan^{-1}(\frac{y_2-y_1}{x_2-x_1)}[/tex]
Given P(-6,0) and Q(2,4) so vector joining by
[tex]\vec{PQ}[/tex] = [2-(-6)][tex]\vec{i}[/tex] + [4-0][tex]\vec{j}[/tex]
[tex]\vec{PQ}[/tex] = 8[tex]\vec{i}[/tex] + 4[tex]\vec{j}[/tex]
now, the magnitude [tex]\vec{PQ}[/tex] will be
⇒ [tex]\sqrt{(8^2+4^2)}[/tex]
⇒ 8.944
The direction of the vector [tex]\vec{PQ}[/tex] will be
⇒ [tex]\tan^{-1}(\frac{4}{8})[/tex]
⇒26.57°
So, the magnitude of PQ is around 8.944 and the direction is 26.57° from the positive x axis so it's north of the east.

Samantha correctly answered 36 out of 48 questions on a test. She must score 70% or greater to pass the test. Did she pass?
Answer:
Yes
Step-by-step explanation:
You see that you need a percentage. You are given the amount that she got wrong, assuming the questions are weighted the same, you divide 36 by 48. This gives you .75. Then you multiply .75 by 100% giving you 75%.
Every year, the value of a car decreases by 15% of its value in the previous year. If the value of the car was $86,700 in 2012, find its value in 2010.
Answer:
$112,710
Step-by-step explanation:
so first we have to find what is 15% of 86700
so 15/100×86700=$13005
so it is written that 86700 is in 2012 means 2010 it will be
2 times more which means 30% that means just have to do is multiply it two times which makes it $26010
so $86700+$26010=$112710

Find the percent rate of change for each
function and tell whether it shows
exponential growth or decay.
a) y = 110(.95)
b) y = 1.08(1.07)
plz help!!
Answer:
Step-by-step explanation:
a) f(t) = 110(0.95)^t
0.95<1, so the function shows 5% decay
b) f(t) = 1.08(1.07)^t
1.07 > 1, so the function shows 7% growth

Subtract 1 from both sides
[tex]x = 5x + 12[/tex]
Subtract 5x from both sides

Marisa’s mother is driving her to a doctor’s appointment in a town 75 mi. away. If they travel at a constant rate of speed of 50 mph, how long will it take to get to the doctor’s office? A. 1 hr. B. 1.5 hr. C. 2.5 hr. D. 3 hr.
Answer:
B) 1.5 hr
Step-by-step explanation:
75 miles/50 mph = 1.5 hrs
Answer:
B.1.5
Step-by-step explanation: We can already add 1 hour to the answer since 75 minus 50 would be 25. Next, we know that 25 is one half of 50 so that would result in us adding half an hour or 0.5. Now we can add. 1 plus 0.5 results in 1.5

m∠R=140 and m∠S=100. Find the m∠T. The diagram is not on the scale.
Answer:
m<T = 20°
Step-by-step explanation:
m<R = 140°
m<S = 100°
The figure given is a kite. The angles formed where two unequal sides meet are always congruent to each other. This means:
m<S = m<U = 100°
Sum of all interior angles of a quadrilateral = 360°
Therefore:
m<T = 360° - (m<S + m<U + m<R)
m<T = 360° - (100° + 100° + 140°) (substitution)
m<T = 20°
